海外TECH DEV Community javaScript's Array Methods. https://dev.to/hat52/javascripts-array-methods-53lm javaScript x s Array Methods Array is a data structure whichcontains a set of elements Each element take up one index of an array Generally all element of the array are of same type e g string integer etc but this is not the case in JavaScript You can literally add any type of element in an array example Hello world this is doable in JavaScript After discussing what array is lets move on to the methods of array in JavaScript PUSHmethod adds elements to the end of an array and return a new length of an array It mutates the original array Examplelet arr arr push newElement it will push the newElement string to the end of the array console log arr output newElement POPas push inserts the new element in the array pop removes the last element of the array It mutates the original array Examplelet arr arr pop it will remove the last element of the array which id in this caseconsole log arr output shift removes the first element of the array and return the removed element and also mutates the original array and its length Examplelet arr arr shift it will remove the first element of the array which in this case is console log arr output unshiftas shift removes the first element of the array unshift add the new element in the start of the array and return the new length of the array Examplelet arr arr unshift it will add the new element in the start of array and will return the new length of arrayconsole log arr output slice returns selected elements of an array as a new array without mutating the main array it accepts one or two arguments slice method also accepts both positive and negative arguments positive will start from the start of an array and negative will start from the end of an arrayExamplelet arr signal argumentlet newArray arr slice it will return the element from the second index to the last indexconsole log newArray output Two argumentslet newArray arr slice it will return element starting from the start argument to the end argument but does not include the end argument console log newArray output Negative argument singal argumentlet newArray arr slice console log newArray output Two argumentslet newArray arr slice console log newArray output splice add removes elements in an array at specified place It mutates the original array Example Add items to arrayconst arr arr splice it will add after console log arr output remove elements from an arraylet arr arr splice first argument is the position and the second argument is the number of element you want to remove pass if you don t want to remove any element console log arr output add and remove item at same timelet arr arr splice it will remove one item from third index and add two items there console log arr output join return a new string of an array elements either separated by comma or specified separator Examplelet arr const joinString arr join it will return a string of array elements separated by console log joinString output specifying a separatorconst withOperator arr join with output withwithwithwith toString converts an array into string separated by comma This method is not specific for array only it can be found in every object Examplelet arr const arrayString arr toString output forEach loops through each element of an array and executes the callback function for each element of an array Examplelet arr var sum arr forEach function element sum sum element element console log sum output Explanation For each iteration of forEach element s value will be changed for first iteration its value will be then for next iteration its value will be and so on and each value will be added to sum filter returns a new array that filters out the elements of an array If an element satisfies the condition of callback then it is added to the new array Example let arr var filteredArray arr filter function element it will only add those elements to the new array which are either equal to or greater than return element gt console log filteredArray output includes check if an array contains the element passed to the method It only returns true or false Keep in mind includes is case sensetive Examplelet arr red blue yellow green const check arr includes red console log check outputtrueconst check arr includes white console log check output falsemap iterates through each array elements and call the provided callback function for each element of array It returns a new array and does not alter the main array Examplelet arr var newArray arr map element gt element it will multiply with each element of array and store it in the new array console log newArray output from creates and array from an object which have length property or is iterate able Exampleconst arr Array from It will create a new array from the string provided in the from parameterconsole log arr output from also accepts a map function const arrMap Array from x gt x it will first create an array from the provided string and then it will run map function on it console log arrMap output concat Merges two or more array into a new single array This method does not alters the existing array instead it returns the new array Examplelet arr arr const concatedArray arr concate arr this will add both the array in new array console log concatedArray output if you want to merge more than two arrayconst concatedArrayMultiple arr concate arr hello world console log concatedArrayMultiple output hello world reverse reverses the order of the elements of array first element becomes the last and last element becomes the first element it alters the original array Examplelet arr arr reverse it will reverse the array console log arr output sort It sorts the array according to the provided function if the function is not provided then its sorts the array in ascending of UTF It alters the original array and return the sorted array Sort is also case sensitive Examplelet arr arr sort this will sort the array in ascending orderconsole log arr output to sort the array in descending order we have to provide a function to itlet arr arr sort function a b return b a it will sort the array in descending orderconsole log arr output every tests weather all the elements of an array pass the test implemented by the provided function If an element fails the test it will return false and will not run the test for the remaining elements If all the elements pass the test then it will return true it does not alter the original array Examplelet arr const value arr every function element return element lt It will return false because not all the elements are less than or equal to it will return false after it check because does not passes the test console log value outputfalse What if all elements pass the testconst value arr every function element return element lt it will return true because all the elements in the array are less than console log value outputtruesome tests whether any element of an array pass the test implemented by the provided function It returns true if an element of an array pass the test and returns false if no element of an array pass the test If an element passes the test then it will not test the remaining elements Examplelet arr const value arr some function element return element gt it will return false because no element in the given array is greater than console log value output false What if an element passes the testconst value arr some function element return element it will return true because is present in the array and after finding it will not test the remaining elements console log value outputtruereduce executes user provided reducer callback function for each element of an array It passes the return value of previous elements callback function to the next elements callback function and in the end it returns a single value The easiest way to understand this is to get the sum of an array s element using reducer Examplelet arr const sum arr reduce function prevValue currentValue return prevValue currentValue console log sum outputfindIndex it returns the index of the first element of an array that satisfies the provided callback function Examplelet arr const index arr findIndex function element return element it will return the index of if it finds it in the array otherwise it will return console log index outputConclusionDid you guys find the methods that I have listed above useful If you have any suggestion leave them in the comments That s all from me Bye 2021-11-03 07:42:53
